The memory of last summer's high gas prices still stings. Policymakers and environmentalists calling for cleaner, more efficient cars has lead to the largest push for increased fuel efficiency in U.S. history.
Congress passed legislation in 2007 requiring cars and trucks to meet or exceed 35 mpg by 2020. Now, the Department of Transportation has unveiled new improved fuel economy standards.
Combined fuel efficiency of 2011 model cars and trucks must be 27.3 mpg, a 2 mpg jump from the existing standard. Another step toward the 2020 goal.
What about fuel efficiency for existing cars and trucks?
Heavier vehicles require more fuel to move. Companies with large delivery fleets are experimenting with lighter materials to reduce overall weight - and save fuel.
And if you're in the market for a new car, EPA's green vehicle guide can assist in choosing the best, most fuel-efficient car or truck that's right for you.
